How to use #39ae2c

Derived from its contrast, chroma and lightness — not from taste.

Works well for
  • Text and icons on dark surfaces
  • Primary buttons and calls to action
  • Focus rings, active and selected states
  • Headers, footers and dark-mode surfaces
  • Brand accents, badges and data highlights
Use with care
  • Text of any size on white — fails WCAG AA
  • Full-page backgrounds — tiring over long sessions
  • Black text placed on it
  • Status meaning — pair it with an icon or label, never colour alone
  • Pairing with a same-lightness hue — edges vibrate
Minimum size as text on white
Not as text
Safe as a fill behind white type
No — use #21661A
Safe as a 1px border on white
No — use #38AA2B

Meaning and mood

What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.

safegrowingnaturalpermissive

Green means go, well, and grown. It carries finance, sustainability and health with almost no explanation needed.

This is a confident chroma: strong enough to lead a brand, restrained enough to live in an interface all day. The low lightness adds weight and formality.

Worth knowing

Red/green pairs are the most common colour-blindness failure — never let the two carry meaning alone.

#39ae2c, answered

What color is #39ae2c?

#39ae2c is a dark vivid green, closest to Lime Green (ΔE2000 8.3). It sits at 114° on the hue wheel with 60% saturation and 43% lightness, which reads as cool.

What is the RGB value of #39ae2c?

rgb(57, 174, 44) — 57 red, 174 green and 44 blue out of 255, or 22.4% / 68.2% / 17.3% by channel.

What is #39ae2c in HSL and HSV?

hsl(114, 60%, 43%) and hsv(114, 75%, 68%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #39ae2c a light or a dark color?

It is a mid-tone. Relative luminance is 0.3132 and perceived brightness is 54%, so black text on it reaches 7.26:1.

Should I use black or white text on #39ae2c?

Black. It scores 7.26:1 against #39ae2c, versus 2.89:1 for white — AAA at any size.

Is #39ae2c accessible on a white background?

#39ae2c on white scores 2.89:1, which fails WCAG AA at every size. Darken it to #2C8522 to reach 4.5:1, or #216519 for 7:1.

What is the complementary color of #39ae2c?

#A12CAE sits directly opposite on the wheel. Softer options are the split-complements #602CAE and #AE2C7A, which give the same contrast with far less vibration.

What colors go well with #39ae2c?

For interface work: #F5FAF4 as the surface, #C4EDC0 for borders, #539B4B for secondary text, #8228B2 as an accent and #21661A for hover and pressed states. For a palette, the analogous pair #7AAE2C and #2CAE60 stays calm, while #A12CAE is the loudest partner.

What is #39ae2c in CMYK for printing?

cmyk(67%, 0%, 75%, 32%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #39ae2c warm or cool?

Cool — it scores 60 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #69AE2C; nudged cooler, #2AB04E.

Which Tailwind color is closest to #39ae2c?

The green family — its 500 step is #22c55e, ΔE2000 8.1 away. That is a visible difference, so define #39ae2c as a custom token rather than reaching for the built-in.

How do I use #39ae2c in Tailwind CSS?

Inline it as an arbitrary value with bg-[#39ae2c] or text-[#39ae2c], or register the whole ramp under theme.extend.colors.brand so you get bg-brand-500 and friends. The generated 50–950 scale on this page is ready to paste into your config.

What is #39ae2c with 50% opacity?

rgba(57, 174, 44, 0.5), or #39ae2c80 in eight-digit hex. Over white that composites to #9CD796; over black, #1D5716.

Is #39ae2c a web-safe color?

No. The nearest web-safe colour is #339933, ΔE2000 6.9 away. The palette only matters for legacy displays and some email clients now.

What does the color #39ae2c mean?
